New digital technologies may keep the United States Postal Service alive.
Mailboxes that let users print out documents along with other technological advances may be on the horizon.
The USPS faces mounting losses reaching over $3 billion.
Many countries are looking at ways of integrating electronic and hard copy delivery of packages.
Will email soon replace the letter? Some experts say the writing is on the wall for the friendly local mail carrier even as new forms of digital document delivery are beginning to make inroads.
E-commerce has dealt a big blow to the U.S. Post Office. First-class mailings have dropped by half in the past decade and the agency is losing $25 million a day. It's considering cancelling Saturday and perhaps Friday delivery.
"The very idea of the letter is becoming rapidly extinct," said Jeff Jarvis, author of "Public Parts: How Sharing in the Digital Age Improves the Way We Work and Live" and professor of journalism at the City University of New York. "With the shift of marketing dollars from paper to digital, at the same time with the growth of parcel delivery (by private firms), we're going to see continuing disruption. That changes everything about the postal service."
